A Jathera is a shrine constructed to commemorate common clan ancestors. Each village in the Punjab has a Jathera which can be visited by members of different surnames. Many villages have a Jathera for each clan/surname.
When members of a clan form a new village, they continue to visit the Jathera in the ancestral village. If this is not possible, a link is brought from the old Jathera to construct a new Jathera in the new village.
People visit the Jathera when getting married, on the 15th day of the Indian month, and sometimes on the first Sunday of an Indian month.
